Interesting info on the velocity stack oil pan.
Any pics?

I'd love to know what a tuned length exhaust into one of David Vizard's Pressure Wave Termination Boxes does for a 1 cylinder engine, that you want to be efficient AND quiet.
ie: Lots of (free flow?) mufflers; A glass pack for high frequencies and a resonator for low and/or Helholtz or Quarter Wave Resonators. (especially for constant rpm engines) and ???

He gets into them around here:

Then; if/when one of these engines gets old n smokey and its time for a rebore etc; it'd be great if you experimented with Boric Acid on it so others here actually believe me!

I've spoken on it some around here recently:

And have done it (to unbelievable effect!) AFTER learning all the ins and outs.
